i had replaced my former M4R network with a BE85. I have 3 such units installed via Ethernet in our house.

Our bedroom equipment connects to the main BE85 in the living room, thus, having a weaker signal.

I wanted to use one of the M4R in our bedroom, connected it via Ethernet cable, tested the cable with the Mac first, then added the M4R to the network. It is found and connects to the network but not via Ethernet cable. I tried Ethernet 1 and 2, but it makes no difference. 

I had tried different Ethernet cables (all cat-6) but still, the M4R only connects to the main network via WiFi.

Is there anything else i need to can do to change the connection to Ethernet?
